New Guinea Impatiens plant named ‘Kiadime’

ABSTRACT

A new and distinct cultivar of New Guinea Impatiens plant named ‘Kiadime’, characterized by its rounded, upright and compact plant habit; freely branching growth habit; bushy appearance; variegated foliage; freely flowering habit with flowers held above and beyond the foliage; and red purple-colored flowers.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Impatiens hawkeri cultivar Kiadime.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the cultivar name Kiadime.

The new Impatiens is a product of a planned breeding program Inventor in Gensingen, Germany. The objective of the breeding program is to develop new Impatiens cultivars with interesting and unique flower and foliage colors.

The new Impatiens originated from a cross-pollination made by the Inventor in October, 1998 of a proprietary Impatiens hawkeri selection identified as 97-283, not patented, as the female, or seed parent, with a proprietary Impatiens hawkeri selection identified as 97-515, not patented, as the male, or pollen parent. The cultivar Kiadime was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Gensingen, Germany in March, 1999.

Asexual reproduction of the new cultivar by terminal cuttings taken at Gensingen, Germany, since May, 1999, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kiadime’. These characteristics in combination distinguish ‘Kiadime’ as a new and distinct Impatiens cultivar:

1. Rounded, upright and compact plant habit.

2. Freely branching growth habit; bushy appearance.

3. Variegated foliage.

4. Freely flowering habit with flowers held above and beyond the foliage.

5. Red purple-colored flowers.

Plants of the new Impatiens differ from plants of the female parent, the selection 97-283, in the following characteristics:

1. Plants of the new Impatiens and plants of the selection 97-283 differ in leaf coloration.

2. Plants of the new Impatiens have more rounded flowers than plants of the selection 97-283.

Plants of the new Impatiens differ from plants of the male parent, the selection 97-515, primarily in leaf coloration as plants of the selection 97-515 do not have variegated leaves.

Plants of the new Impatiens can be compared to plants of the cultivar Kinoc, disclosed in U.S. Plant Pat. No. 10,433. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Impatiens differed from plants of the cultivar Kinoc primarily in leaf coloration as plants of the cultivar Kinoc did not have variegated leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Impatiens. The photograph comprises a side perspective view of three typical flowering plants of ‘Kiadime’ grown in a 22-cm container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Kiadime has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photograph and the following observations and measurements describe plants grown in Encinitas, Calif., during the late spring, under commercial practice in a polyethylene-covered greenhouse with day temperatures about 24° C., night temperatures about 18° C., and light levels typically about 4,000 foot-candles. Plants used in the photograph and following description were about 14 weeks old and grown in 22-cm containers with three plants per container.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
